iPhone connects and disconnects from Mac

I have been suffering with this issue since I got the MacBook, I chose to avoid the problem by using my windows 10 laptop but I want to use the photos app as my iPhone X 256GB is full! has anyone got an actual solution for this as the ones I've tried on here will not work. We don't have an apple shop here in New Zealand so it's difficult to get it looked at.

Thanks,

John.

I have the same problem. I tried doing things below, but it didn't work.

The problem was fixed when i switched from a third party usb cable to one made by apple and pushed the end of the charger a little. Before that, i was using an anker charger(tried doing ^ but it didn't work).

The small battery symbol on the top right of my iPad was going on and off, so I thought that there was some problem with the connection from the usb cable to the computer.

Cleaning out the hole that the usb goes in, or pushing the usb end a little next to the computer's input will cause the cable to have a secure connection from the pc/laptop to your iPhone/IPad.

i hope this works for you.

The thing is, I am using Apple cables, and other i-devices seem to be able to connect to my MacBook Air just fine. This also happened with a previous iPad that I had the same info in. The problem, for me, is that something is wrong with the internal software? (I’m guessing, since anything else works and after backing up my 2nd iPad doesn’t work).

Tried connecting when my phone was on ~16%, didn't work until I switched my phone to low power mode. Then connected with no problems. Tried many of the other fixes on this page, that may have led to it finally working on low power mode...

from THISISYOURANSWER: Connect your iphone to your Mac.

Go to Activity Monitor --> Search for usbd --> Force quit it.

only solution that worked for me!!!! after digging into the comments. thank you!

using an iPhone XS Max and a Macbook Air.

golly. i even bought a new cable! thought it was the cable.

thank you @thisisyouranswer . xxx

I'm having the same issue here but just with my husband iPhone 7 Plus. Mine works pretty fine but it's an iPhone 6.

MacBook Pro Retina, 13-inch, Mid 2014 - MacOS Mojave 10.14.3 with iTunes 12.9.2.5

iPhone 7 Plus iOS12.1.4

iPhone 6 iOS 12.1.4

Apple lightning cable

One thing that I've noticed is that killing usbd via Activity Monitor worked here but it turned the personal hotspot on in the iPhone 7 Plus. And when I turned the personal hotspot off, the issue restarted immediately. Have anyone noticed that too?

I followed the suggestion regarding power. My iPhone x was at 37% and pulled the cable from my Macbook pro, plugged in a powered USB hub, then plugged my iPhone into the hub. No more issues.

It ****** me off that Apple couple not provide an answer about this problem and we had to figure out how to get around it. I wish Tim would stop worrying about promoting his gay agenda and get back to running the business.

I am having the same issue. But, I have found that it only occurs when my computer is charging. If I disconnect the charging cord, my iPhone stays connected. Not sure why this works, but for some reason it does.

I solved this by connecting my iPhone 6 at the same time. My Macbook only connect to the Xs Max whenever I plugin the iPhone 6, eject the 6 then happen again.

Totally not expect this. Lmao. What feature is this?

I have been having this problem for a loooooooong time. Tried every recommendation I could find, none of them worked, and finally found out about SMC reset which is recommended for port issues in general. This fixed my problem -at least for now-.

I found a workaround (didn't solve but you can charge like theres nothing wrong IF you do this every time that happens).

When it starts connecting and disconnecting you put the iPhone on Low Power Mode: ON and reduce the screen brightness all the way down tils its dark. You'll notice that it will stop doing the Connect/disconnect dance and just charge, slowly but still charge.

Worked for me for some time now. Usually original cables and wallplug doesn't need this workaround. Problem shows up for me when using not original cables or usb from pc, macs, other gadgets chargers and so on.

If it works for you, please let me know. I wanna spread the word cause I never found a workaround on the internet and wanna help those frustaded iPhone users.

At.

I have tried literally everything I read on internet and still couldn’t fix it, so I turned off my macbook and turned it back on while iphone was still plugged in and it connected and stayed connected..when I unplugged it and tried it again it kept doing the same connecting/disconnecting thing. So I would suggest just restart your MacBook while iphone is still plugged in on the usb port and see if it solves the issue when it turns back on.

Having the same issue. I've tried everything posted here and none of it resolved the issue. Just tried this my final hope and now I'm unable to even get to iTunes to accept. Phone keeps beeping and vibrating...so frustrating !

I was having this exact issue and my brother and I tried ever troubleshooting thing you could think of and nothing would work. I finally tried again just for the sake of it after my phone was had charged up some and it now connects with no problem! When I was initially trying to connect my phone was close to dying and only had about 13% remaining, but after I got 50+% CHARGED no issues what so ever!

I HOPE THIS HELPS SOMEONE!!!

This is most annoying. I'm having these issues with a USB connection between iPad or iPhone connecting to iMac. Only solution is to force quit USBD from Activity monitor (or terminal method). This solves it while iPad or iPhone is connected. Once devices are disconnected, this will happen all over again when next plugged in.

When force quitting USBD and as an indicator that things are not right when plugging in device afresh, device constantly asks me to enter PIN number to trust device...

It's not - energy based (ie battery less than 60%)

It's not - a cable issue

It's not - Reset Location & Privacy settings on iPhone or iPad

It's not USB port on iMac - others have same results

Because it doesn't happen with same devices and cables at all when I connect iPhone or iPad to MacBook Pro.

Restarting iMac doesn't help either.

Any ideas what can be done here?

Thanks
